In 1930, the coconut palm became Hawaii’s official tree and served this role until 1959. On May 1, 1959 the 30th Territorial Legislature of Hawaii approved the Kukui or candlenut tree, Aleurites moluccana, as the state’s official tree. Read more about the Kukui tree’s special place in Hawaiian culture in Jason Moore’s, Maui No Ka ‘Oi Magazine article, The Tree of Light .
